[1.7.2] How to code a forge mod in scala

Recommended Posts

I suppose you've used proper tutorial for deploying Forge 1.7 build environment.

Then you should know that Eclipse project is generated from Gradle and thus changes to it won't do any good.

Next, you'd have build.gradle look this way:

repositories {
... // repos config, not our case
}

apply plugin: 'scala' // Here our hero comes
apply plugin: 'forge'

... // rest of Gradle config

and then re-generate Eclipse project with

gradlew eclipse

Also, you need to respect default source layout for Scala or override it

http://www.gradle.org/docs/current/userguide/java_plugin.html

http://www.gradle.org/docs/current/userguide/scala_plugin.html

Last, to see Scala cookes in Eclipse you need to use Scala perspective. Though you should know this if you intend to write in Scala.

 

One of good examples would be ForgeMultipart: https://github.com/Chicken-Bones/ForgeMultipart

It's in Scala, it's a coremod, it's for 1.7 and it's using ForgeGradle.

 

Last advice. Store your launch config as shared and keep it versioned. ForgeGradle doesn't create proper run configurations for you.

 

If you gonna learn Scala by writing your first mod then I wouldn't recommend doing this because Scala is rather complicated and has steep learnring curve. I'd recommend attending these Scala courses on Coursera:

Minalien made a great tutorial for using Scala and the IntelliJ IDEA IDE: http://minalien.com/tutorial-setting-up-forgegradle-for-intellij-idea-scala/

if (user.hasKnowledgeOfJava) {

    if (user.question.hasCode) {

        return interpetHelpfulResponse(user.getQuestion());

    } else {

        return "Could you post your code please?";

    }

} else {

    return "Learn some freaking Java!";

}

No , It doesn't work. While I create the source folder, eclipse thinks the scala code was java code. How can I fix this?

As I said above, Eclipse project is generated from Gradle. Assume it as some generated code. Next, re-check info on Gradle's Scala plugin. You'll see that your sources should be in src/main/scala. Or override Scala source location manually. Investigate ForgeMultipart's build.gradle. Otherwise, specify exactly what you do, what you expect to happen and what went wrong.

But Thanks everyone by advance to help me with this.
    • These forums are for Minecraft Forge, not Fabric. You would probably be better served posting this question wherever fabric support is given, most likely their discord server.
    • Add the new latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here
    • Update: I tried to reproduce the bug and found out that if I place a flare on a block and then dismantle it with the pickarang (Quark), the flare gets no NBT Tag after getting assigned an empty one through the offhand.
